Hey folks. I've been having an issue with the

atlastCidrBlock

in a managed

mongodbatlas.NetworkPeering

resource using the Node version of pulumi. The option seems to have no effect and the created resource seems to always have the default value of

192.168.248.0/21

.

export const atlasPeer = new mongodbatlas.NetworkPeering('atlas-peer', {
  providerName: "AWS",
  awsAccountId: AWS_ACCOUNT_ID,
  vpcId: VPC_ID,
  projectId: ATLAS_PROJECT_ID,
  containerId: mongoCluster.containerId,
  accepterRegionName: AWS_REGION,
  routeTableCidrBlock: '10.11.0.0/16',
  atlasCidrBlock: '192.168.232.0/21',
});

This snippet creates a stack output of

{
  "accepterRegionName": "us-west-2",
  "atlasCidrBlock": "192.168.232.0/21",
  "atlasGcpProjectId": "",
  "atlasId": "XXXXXXXXXX",
  "atlasVpcName": "",
  "awsAccountId": "999999999",
  "azureDirectoryId": "",
  "azureSubscriptionId": "",
  "connectionId": "pcx-XXXXXXXX",
  "containerId": "XXXXXXXXXX",
  "errorMessage": "",
  "errorState": "",
  "errorStateName": "",
  "gcpProjectId": "",
  "id": "XXXXXXXXX",
  "networkName": "",
  "peerId": "XXXXXXXXX",
  "projectId": "XXXXXXXX",
  "providerName": "AWS",
  "resourceGroupName": "",
  "routeTableCidrBlock": "10.11.0.0/16",
  "status": "",
  "statusName": "PENDING_ACCEPTANCE",
  "urn": "urn:pulumi:staging::journey::mongodbatlas:index/networkPeering:NetworkPeering::atlas-peer",
  "vnetName": "",
  "vpcId": "vpc-00000000"
}

...with an

atlasCidrBlock

of

192.168.232.0/21

, though the created peering connection instead has the default Atlas CIDR of

192.168.248.0/21

, as does its corresponding route table entry on my aws side. Interestingly, the stack output's value for atlasCidrBlock doesn't even change across

pulumi refresh

operations. Is it possible I'm doing something wrong? If not, is this most likely a bug with pulumi or with atlas? Thanks!

That looks like a pulumi or atlas bug. Might be pulumi isn't sending the attribute, might be atlas is ignoring it. I'd suggest raising an issue at https://github.com/pulumi/pulumi-mongodbatlas/issues
